Ken Levine's Twitter feed reveals that BioShock Infinite will not include any form of multiplayer support. The designer expressed skepticism early on about the inclusion of multiplayer in Irrational's shooter sequel, though a recent job posting seemed to indicate it would indeed be part of the game. Now in a series of responses to questions about multiplayer support, he puts several nails in the coffin for this prospect, saying: Nope, No Multi, No MP in Infinite to being badgered about the prospect, leading to an exasperated retweet: "Thank sweet baby Jesus no multi ---That's exactly the reason we don't have it. That kid is persistent." Thanks nin via Kotaku.

They were working on it before, trying to make the whole skyrail thing work in a deathmatch setting for consoles. AFAIK they spent a lot of time and money on that, but just couldn't be satisfied with it, and then whatever other problems they've had in development finally put the nail in its coffin. You bet your ass 2K wanted multiplayer in this... they don't care if it sucked in BioShock 2, it was an extra selling point for them that brought in at least some players that may not have been interested otherwise, plus it's easy to churn out little maps for DLC.
